For HoloLens creators

There is an additional rendering setting that needs to be set in Unity so that the scene renders correctly. If it is not set, asset bundle content that is viewed on HoloLens will be viewed only through one eye, which very uncomfortable for HoloLens users.This setting is very important.

​
To set the HoloLens rendering mode to Single-Pass Instanced.

Under File -> Build Settings, switch the Platform to Universal Windows Platform. Then select the Player Settings button in the lower left hand corner of the Build Settings menu to bring up the Project Settings. 948 Inside of the Project Settings, go to OpenXR under XR Plug-in Management. Set Render Mode to Single Pass Instanced. 1030 Now select the Switch Platform button to apply these settings. (Don’t worry if you are doing work for other devices like PC or iOS, switching platforms will NOT be required for each device.) 940
